dsh-win-minimal: DeepSeek Harness Minimal Mode on Windows

The `dsh-win-minimal` plugin provides an alternative to the `minimal preset` for DeepSeek Harness (DSH) on Windows. It retains the one-line fixed persona, zero runtime context, and automatic compression, and integrates the three tools: gitbash, str_replace_editor, and web_search. After installation, users can select “Minimal Mode (Windows)” when creating a new session. The plugin can be installed via CLI or DSH Desktop, with files located in the specified directory. It allows users to customize the persona and tools, but requires gitbash to be installed globally.
